However, I wasn't focused on what he was doing; I felt it was all about luck, so personally, I just played slots without paying attention to any particular patterns. So, what about you? Are you one of those people? or are you just a casual player like me? If so, please give your reasons.
It would have been better if you told your friend to teach you the pattern he is using, for him to be predicting it more accurately it means he has been studying that Casino and probably knew some secret. If you had made up your mind and ask him, maybe he could have opened up for you perhaps you wouldn't have been asking us here to know while you already have a friend who can help you with what you needed.
Those pattern is only just a personal belief of his friend with no basis. The is mixed loses and win which shows inconsistency that proves that it’s not accurate.
I don’t discourage this method if this finding pattern give him more excitement on gambling but technically speaking it’s not helpful at all to increase the winning percentage because it will give same result regardless if you bet with pattern or not on slot games.
There’s no way the game provider will leave a pattern that can be use for exploiting their games.
